Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force leading to thread stripping or bolt breakage, especially in softer materials.Always use a torque wrench to apply the manufacturer-recommended torque for the application and material. Avoid 'feel' tightening.
Selecting the wrong screw length, resulting in insufficient engagement or protruding threads.Ensure the selected screw length provides at least 1.5 to 2 full thread engagements in the mating part for optimal holding power.

Common Applications

  • Marine hardware and fittings
  • Electrical connectors and enclosures
  • Decorative and architectural components
  • Plumbing and water systems
  • Scientific and laboratory equipment

⚠️ Engineering Warnings

  • Brass can be susceptible to dezincification in aggressive acidic or chloride-rich environments. Verify suitability for specific corrosive media.
  • While brass offers good conductivity, it is not as conductive as copper or silver. Consider alternative materials for high-power electrical applications.
